I'm done with Case too, but for a different reason: I just literally have enough of them.
The last time I bought new Case knives was the end of 2014 - a late Christmas gift to myself. I bought a batch of five at that time, all for very good (low) prices over the Internet.
I'm happy with all five of them, and four of them get regular carry and use. I have two from that batch with me today, in fact, and a third is in my car.
I don't know what their current production is like. Most of mine run from about 2008 through 2014, with a few older ones from the 70s, 80s, 90s. I've probably got somewhere between 80 and 100 Case knives. Some were bought new from dealers (mostly on-line, a few in stores) and some were purchased used through forums or ebay.
Some of the new ones had a few cosmetic issues that I was able to resolve, but none had any problems I considered worth sending in for repair or returning to the dealer.
To JDs original issue - if I had spent that much on a Case knife and it had the problems he reported, I would do the same thing and send it back. I just haven't had that experience myself.
